Subsonic 4.5 - Commas in folder names throw Java error

[MediocreFred]

Hello,

I just upgraded Subsonic from 4.4 to 4.5 yesterday and have been struggling to fix this problem. Would appreciate any help.

Environment: Subsonic 4.5, Windows 7 x64, Java 1.6.0_29. Theme: Slick (tried default too).

I have numerous folders with commas in the folder name (usually in cases where it's the name of the artist in a "last name, first name" format. The left pane/frame chokes on folders with commas in them. I get the Java stack trace dump that is at the end of this post. Everything worked fine in Subsonic 4.4. Also, commas in subfolder names don't cause any issues - these are displayed and drilled down in the main pane/frame.

I also tried purging the mediafolder cache, all temp files, the lucene folders, the index and everything else I could find. Also tried rebooting.

Is this a bug that can/will be fixed? I would hate to have to rename all my top-level folders that have commas in them. Especially when the right/main pane/frame can handle commas in folders just fine.

This error shows up when any folder name with a comma is clicked on in the LEFT pane.

Code: Select all

Thats weird one.
As a test I just renamed one of my artist folders with a comma in the name and there appears to be np.
I am running on Windows server 2003 (WHS R1) with also java v29.
Here is a screen shot (bit odd cause I had it in wrong setting ) but you get the idea.



Can you confirm that is what your problem is.
If so we may need someone with your os to check their install

As long as Subsonic has cached the MusicFolder list and has built the index, it appears to work fine. Can you please try deleting Subsonic's cache (temp folder) as well as the index. Stop the service before doing this. Then start the service back up. Make sure the folder has the comma in the left pane. Click on it and see if it works.

To narrow it down, I added a new location that just had one top level folder (with a comma). Clicking on it guarantees the error. Also, at the top of the left pane, there is a dropdown list of locations (folders). Selecting this new location generates the same Java error in the left pane. SO, I don't even see the tree in the left pane. If I remove the comma from the folder name, everything works fine (sometimes it fixes itself right away and other times I end up having to delete the cache file in the temp folder).

Thanks,
MediocreFred.
